That's an interesting idea.....I'm glad to see NECA has re-vamped their web-site; prior versions seemed to say only utilities could be members!
NECA does go on to say that 99% of their memebers are "union" companies....so I suppose the "trade group" for electricians is the IBEW!

The IAEI is, naturally, focused on inspectors. And the NFPA can't seem to get a bulliten board going, either.

Maybe ECN will be the place where this all gets started.....
